Be it known that we,W1LLiAM WHITE and SPENbnn OTIS, citizens of the United States, residing at Chicago, in. the county of Cook and State of Illinois, have invented certain new and useful Improvements in Systems of Washing and Filling Locomotive-Boilers, of which the following is a specification.

Our invention relates toelocomotive-boiler 'ashing and filling devices; and has for one 0.. its objects to provide a system in which the water blown from locomotive-boilers .be cleaned and the impurities therein separated therefrom and the cleaned water used for washing out boilers to remove sedi ment and scale therefrom.

Other objects of the invention will appear from-the description hereinafter.

Our invention consists in the combinations and details hereinafter set forth and claimed. a

In the drawin we have illustrated a boiler washing and fil ing system constructed in accordance with our invention.

In the drawings,'a represents a tank for receiving water blown from locomotive-boilers, which wateristo be used for washoutwater. The water from the boilers is conveyed therefrom through a suitable pipe c to a filter and separator b, containing an upper chamber- 6'' and a lower portion b',.the lower portion containing suitable filtering material. A pipe 12 leads from the upper chamber 1) to a sludge-receptacle I).

It will be understood that the water blown out from the boilers is mixed with steam. Upon reaching the filtering and separating devices the steam and the water are sepa rated, the water passing through the filtering material through the pipe 1- to the tank a. I The steam passes through a piped, leading from the separator-chamber to a heating device e, hereinafter described.

g represents a cold-water line containin a pressure-reducing valve 9 of any suita 1e construction, the function of this valve being to regulate the pressure in the cold-water line, so that it may be the same as the pressure in the washout-line, the washout-line being indicated at h and leads from the washout-water tank to 'a point where the water is to be used.

Iris a pump, type-as, for instance, a rotary forcing water from the tank a to t n is a cross in the washout-line,

which may be of any desired pump-for e line.

As will be readily understood, when the water in the washout-line varies from a cere line as hitherto considered necessary and introduce from the cold water line.

eing conveyed to the tank tank f, this wat from the heater throu h the pipe e-,.-leading e. ater is admited to the u per part of the heater e througha pi ee eading from a suitable source of supp y, the amount of water admitted being controlled by a float a, controlling, through suitable connections e e, a valve e in the admission-pipe. The heater is rovided with plates e, having alternate p ates having central passage-ways e and side passage-ways 'e", respectively, so that the water is compelled to take a circuitous course in its travel from the top to the bottom of the heater. As before described, steam blown from the locomotive is admitted through the lower part the pipe (1 and rises through the heater in a direction contrary to the travel of the incoming water, which is thus heated, owing to its contact with the steam. l 'iheater such as above described is commonl known in this art as an F open heater 1 and is distinguished fromthe closed heater, which is sometimes used, byreason of the fact that in the open 1 blown into the heating-chamber and there comes into direct contact with the incoming water, whereas in heaters of the closed type chamber in pipes, the incoming water being heated by its contact with the heated pipes.

represents a thermostat in the filling-we tertank controlling a diaphragm-valvev f 2 in a live-steam 1ine. When the water in the filling-tankfalls below a predetermined temperature, the thermostatically controlled valve f 2 will operate to admit ive steam to the heater, thus'increasingthe temperature of the incoming water.

tain predetermined temperature the therniorate to It will be apparent that enabled to do away-with the mixing-tank cold water into the washoutline directly Water for fillingfhe boiler is contained in a of the heater through heater the steam is the steam is conveyed through the heating IlO' 'l'he filling-water is spectively.

conveyed from the tank through a pipe-line Z to point of use, a suitable pumpJc operating to force the water from the tank through the line.

71 represents the washout-water-circulating pipe, and Z the filling-water-circulating pipe, thesebeing arranger stood in this class of devices, to maintain a circulation of the washout and filling. water, respectively. m is a pressure-retaining valve located in the wasliout-water circulating line,

this valve bein arranged to close when the washout-line is being used, thus maintaining a proper pressure in the washout-line. When the wash out-line is not 1n use, this valve Wlll open, permitting the circulation of the wash-' out-water through the washout-discharge line It back to the washout-tank through the circulation-pipes h. m is a similar pressureretaining valve located in the circulatingline for the filling-water and acts in a similar manner to retain pressure when the fillingwater line-is in use. It will be understood that the pumps 7c 7r operate to maintain the circulation of water in the washoutand filling lines, respectively.

The operationof our system will be readily understood. It will be seen that we have provided a system in which the entire fluid contents blown out from a locomotive are se arated and mingled with the washout and filling waters to heat the same, the Water blown out from the boiler being filtered and mingled directly with the f washout-water, while the steam after separation is conveyed to the open heater and'mingled' with the fillin -water.
